For example, the content 1601 having the highest priority among the plurality of pieces of content 1601, 1602, 1603 and 1604 may be displayed in a first region 111 of the display 110, and then the pieces of content 1602, 1603 and 1604 may be arranged in order in second to third regions 112, 113 and 114, respectively.
The electronic apparatus 10 may, as shown in
The electronic apparatus 10 may receive a user's input for changing the layout of the screen while the plurality of pieces of content 1701, 1702, 1703 and 1704 are arranged on the screen.
The electronic apparatus 10 may arrange the plurality of pieces of content 1701, 1702, 1703 and 1704 in the regions 111, 112, 113 and 114 of the display 110 based on the received user's input. For example, in response to the reception of a user's input for giving the high priority, e.g., the first priority to the content 1703 having a predetermined low priority, the image of the content 1703 may be rearranged to the first region 111 of the display 110. Therefore, the image of the content 1701 displayed on the first region 111 may be rearranged to the third region 113 based on its relatively lowered priority.
In the foregoing embodiment of
According to the embodiments described above, a user can freely rearrange the multi-view screen by reflecting changes in reproduction environments, content's own characteristics, preferences, etc. through the function for changing the priority of the multi-view content.
